<p>PURPOSE:To expand the scope of material which has been limited in the usage as a package material for a deliquescent drying agent by using a sheet or a nonwoven fabric made of a synsthetic polymer having a permeability for moisture but not for water. CONSTITUTION:As a package material for deliquescent slats such as calcium chloride or magnesium chloride and a high concn. aqueous solution thereof as a drying agent, a sheet or a nonwoven fabric made of a synthetic polymer having permeability for moisture but not for water or aqueous solution is used. By using this package material, a starting material limited in use is made usable and an economical drying agent is obtained.</p> |
